From the book: The 4 Percent Universe Dark Matter, Dark Energy, and the Race to Discover the Rest of Reality (page 55).

Some valuable excerpts:

"The computer he would be using at Los Alamos—a CDC 3600—was many
magnitudes more powerful than any he could have found on a university
campus, and he wouldn't even have to tap the Princeton Physics Department's
research funds." Peebles, 1965.
................
"Peebles would be performing what scientists call an N-body simulation. Take a number—N—of points, program them to interact according to whatever properties you want, and see how the action unfolds. In this case, Peebles would be taking 300 points and treating each as if it were a galaxy in one particular part of the universe—the Coma Cluster, the closest and most-studied galaxy cluster.
He would assign each galaxy a position and velocity based on rough
observations of real galaxies in the cluster, and he would teach the computer the law of universal gravitation. And then he'd let the model do whatever galaxies interacting gravitationally in an expanding universe do over billions of years."
.......................................

Peebles run the simulation many times, making time advance. At each step, he capture the computer screen in a frame of a 35mm film.

"When Peebles had enough frames, he ran them together, loaded
the film in a projector, and sat back.
The universe swirled to life. Galaxies moved outward, following the flow of
the Hubble expansion. But then they didn't. They slowed, also moving under the influence of their mutual gravitational attractions, and they continued to slow, until they stopped following the flow of the expansion and began to fall back on themselves. Smaller galaxies clumped toward the nearest larger galaxies, and those growing clumps clumped with other clumps."

The question is: What theory he used to model this disproof of BB?
Did he used linearized GR or modified Newton?

Using 300 point-like galaxies, he had to simulate 300x299/2 interactions,
roughly 15,000 equations that covered the discrete universe with 300 galaxies.

This is a question to the forum, as I don't to search for the answer.

Remember that it was 1965 and the "supercomputer" power was under
1 million instructions per second. Also, the processing power has increased at least 1 million times since then, and models still don't work,
even using massive super-clusters with millions of galaxies.

So, the question is: what theory is being used to simulate this enviroment during its evolution for billion of years? And why it doesn't work yet?

Hint: He used gravitational attraction, but by which mechanism? Brute force newtonian law of gravitational attraction
or the sophisticated GR theory with his 300 space-bending areas interacting one with every each other?

For more, read the book (except Bodkin, as for him this is vulgar popularization of physics for laymen).

I'm having a feeling that nobody here "can handle the truth".

What? Is GR at peril?

For sure it isn't The Shit; what would a cosmologist do
with its "local time" nonsense?

You made me laugh!

The simulation run time lapses which amounted to billions of years. Local time! LOL

Imagination, poor halfbrain. You can't even read.

And barely sow. The latest advances in the use of the parallax effect allow to
measure movements in our galaxy in a radius of 10,000 light-years.

I quote this excerpt from Wiki:

https://en.wikipedia.org/wiki/Parallax

"The European Space Agency's Gaia mission, launched in December 2013, can measure parallax angles to an accuracy of 10 microarcseconds, thus mapping nearby stars (and potentially planets) up to a distance of tens of thousands of light-years from Earth.[10][11] In April 2014, NASA astronomers reported that the Hubble Space Telescope, by using spatial scanning, can precisely measure distances up to 10,000 light-years away, a ten-fold improvement over earlier measurements.[8]"

It means that, beyond such a radius, we can't measure distance in our own galaxy on its entirety. And yet, cosmologists are promoting
the existence of massive black holes at the center of the Milky Way and, pretty much, at the center of every galaxy in the universe.

But, more audacious, is the resurrection of the famous ABSOLUTE frame of reference (the Cosmic Microwave Background). Due to
this anti.einstenian concept, the ABSOLUTE movement against our galaxy against this frame has been calculated as about 600 Km/sec, and more yet, we are moving locally toward Andromeda. The motion of our solar system has been estimated at 150 Km/sec, toward the
direction of the star Vega in the constellation of Lyra, within our galaxy.

I quote:
https://www.researchgate.net/post/How_can_we_practically_measure_the_velocity_of_earth_in_Cosmic_Microwave_Background_rest_frame

"It is estimated that the Milky-Way Galaxy itself moves at about 600 km/s when measured with respect to a Cosmic Microwave Background (CMB) rest frame.. The velocity of earth with respect to the CMB rest frame may be within a range of 400 km/s to 800 km/s."

So, Einstein, where are thou? And your relativity?

Discuss, if you want to.

Cretin,

The Cosmic Microwave Background Radiation is not a frame of reference.

The gunny thing is that your imbecilities will remain on the internet long after you are dead. Which will only bring shame to your family.

Google it, donut;

"In cosmology, the rest frame for the cosmic microwave background (CMB) appears to be a preferred frame of reference. For example, galaxies tend to have an average speed of zero relative to their local CMB rest frame."

or

"Does the universe have a rest frame? This postulate of relativity implies that there is no resting frame in our universe; otherwise one will be able to determine which inertial frame is stationary and which frame is moving. This means that the vacuum in our universe must be an empty space and thus cannot serve as a reference system."

or

"In theoretical physics, a preferred frame or privileged frame is usually a special hypothetical frame of reference in which the laws of physics might appear to be identifiably different (simpler) from those in other frames."

or

"It seems that we are moving relative to the universe at the speed of ~ 600 km/s. This is the speed of our galaxy relative to the cosmic microwave background."

or

"The CMBR makes our universe a cavity of black body at 2.7k, the radiation is distributed all over the universe and waves do not have a privileged directions. For this reason, by measuring it on a spherical zone, it is used as a rest frame with a very good approximation. This technique is used in order to estimate the relative speed of celestial bodies and it is giving good results. Can it actually be the absolute reference frame Newton was looking for?"

or

"The modern view is that there exists a preferred frame of reference related to the cosmic microwave background (CMB), more precisely to the last scattering surface (LSS), and that our galaxy’s peculiar motion with respect to the CMB produces Doppler effect responsible for the CMB temperature anisotropies.It is evident that the existence of a preferred frame of reference is in contradiction with the fundamental hypothesis of the special relativity which Einstein termed the ’principle of relativity’.A violation of the relativity principle influences also a validity of the principle of universality of the speed of light, in particular its constancy and isotropy, and, in general, implies a violation of the special relativity."

These comments are all around the web. NASA and ESA approves this.

Einstenians don't.

Who will be right? Einstein, we have a problem!
